FREDERICK JAMES I-IAIVORTII HAZARD, OF TORONTO, CANADA.

BICYCLE.

SPECIFICATION forming part of Letters Patent No. 448,960, dated March24, 1891.

Application filed September 6, 1890. Serial No. 364,126. (No model) Toall whom t may concern/.-

Be it known that I, FREDERICK JAMEs HAWORTH HAZARD, manufacturer, of thecity of Toronto, in the county of York, in the Province of Ontario,Canada, have invented a certain new and useful Improvement in Bicycles,of which the following is a specification.

The object of the invention is to provide a simple and substantialspring-support for the seat of a bicycle; and it consists, essentially,of two or more horizontal spring-rods suitably connected to the rigidframe of the bicycle and designed to form a spring-support for the seat,substantially as hereinafter more particularly explained.

Figure l is a perspective View of my improved bicycle. Fig. 2 is adetail of the connection between the spring-rods and the front portionof the rigid frame of the machine. Fig. 3 is a detail of the connectionbetween the spring-rods and the rear portion of the rigid frame of themachine.

In the drawings, A is the seat of the machine, connected in the ordinaryway to the pillar B. This pillar passes through a bracket O, providedwith a set-screw D. The pillar B is vertically adjustable in the bracketO and is held at any desired point by the said set-screw D.

E is a tube connected to the bracket O and through which the pillar Bpasses. This tube E is fitted into a sleeve F, rigidly fastened to thebackbone G.

H is a bifurcated standard, connected at a to the bracket O andextending down to form a double support for the crank-axle I. Each legof the standard II is braced by a rod J, arranged as indicated. On eachleg of the standard II, I tix a bracket K, which has two eyelet-holes,through which the spring-rods L pass. I prefer to arrange these rods inpairs, as indicated; but of course it will be understood that one rod oneach side would be sufficient. The rear end of each rod L is connectedto a block M, pivoted, as indicated, on the rear fork N. As shown, Iprovide one block M for each pair of rods. The front end of each rod Jis connected to a crank-arm O. Fig. 2 shows the means of connectingthese crankarms to the frame of the machine. On refer` ence to thisfigure it will be seen that a spindle P is loosely journaled in theportion of the frame marked Q and that each end of the said spindle isscrewed to receive a crankarm O, as indicated in Fig. 2. The end of eachcrank-arm O is cupped to butt against the hub formed around the spindleP, and in this way the dust is prevented entering the bearing of thespindle P.' From this description it will bc seen that the Weight of theseat A is supported by the spring-rods L.

The manner described of connecting these rods to the frame of themachine permits the said rods to bend sufficiently to give the necessaryspring motion.

Vhat I claim as my invention is-` l. Abicycle havingarigidframe,twospringrods connected by their opposite ends to said rigid frame, and aseat supported on said rods, substantially as described.

2. Two or more horizontal spring-rods connected to the rigid frame of abicycle by means of pivot-blocks or crank-arms, in combination with abifurcated standard connected to the spring-rods, and to theseatstandard, substantially as and for the purpose specified.

3. Two or more horizontal spring-rods L, each supported at its rear endby a block M, pivoted on the rear fork of the machine and at its frontend to a crank-arm O, pivoted to the front portion Q of the frame, incombination with a bracket K, bifurcated standard H, bracket O, andseat-pillar B, substantially as and for the purpose specified.

4. The seat-pillar B, passing through the bracket C, to which it is adjustably connected by means of the set-screw D, a tube E, connected tothe bracket C and movably fitted into the sleeve F, which is fixed tothe backbone G, in combination with a bifurcated standard H, connectedtothe seat-pillar B by the bracket O and to the spring-rods L by meansof the brackets K, substantially as and for the purpose specified.
